Before Mrs Scandalised of 48 Hellinahandbasket Close lunges, gasping, for her quill, an explanation is in order. "I'm not some hippie," says James Wong, his eyebrows assuming the standard calm-down-dear gradient of the pop-science professional. "I'm an ethnobotanist, trained at Kew Gardens."

Following the unprecedented success of his inaugural voyage, the star of Touching Evil III returns to the "intense leisure" fray with more briny ruminations on what it means to fish extremely. In tonight's opener the Geordie casts his net across Canada, where unsuspecting locals and unusually large sturgeon present the actor with further chances to elongate his vowels aboard inexpensive fishing vessels ("WHOOOOAAAAAH MAAAAAAAAN!" etc).
